The General Rufus Putnam Hall was constructed in 1823 by the Olive Branch of the Master Masons. After 1844 it was used as a school and for several years as a meeting place for the DAR. When the first-floor schoolroom was vacated it became space for the Town Library. In 1984 the Library was moved into the Town Hall and the Town voted to allow the Historical Society usage of the building. Today, the building houses the Rufus Putnam Museum and Office, displaying artifacts from local history.
